A shared effect of paroxetine treatment on gray matter volume in depressive patients with and without childhood maltreatment: A voxel-based morphometry study. CNS Neurosci Ther 2018; 24:1073-1083. [PMID: 30277663 DOI: 10.1111/cns.13055] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Revised: 08/01/2018] [Accepted: 08/01/2018] [Indexed: 12/28/2022] Open
Abstract
AIMS This study assessed whether antidepressant drug treatment has a common effect on gray matter (GM) volume in MDD patients with and without childhood maltreatment (CM). METHODS T1-weighted structural magnetic resonance imaging data were collected from 168 participants, including 51 MDD patients with CM, 31 MDD patients without CM, 48 normal controls with CM, and 38 normal controls without CM. MDD patients received 6 months of treatment with paroxetine, and 24 patients with CM, and 16 patients without CM received a second MRI scan. A whole-brain voxel-based morphometry approach was used to estimate GM volume in each participant at two time points. Two-way analysis of variance (ANOVA) was used to determine the effects of MDD and CM on GM volume at baseline. Repeated measures two-way ANOVA was used to determine the treatment-by-CM interactive effect and main effect of treatment during paroxetine treatment. We further investigated the relationship between GM volume and clinical variables. RESULTS At baseline, significant MDD-by-CM interactive effects on GM volume were mainly observed in the left parahippocampal gyrus, left entorhinal cortex, and left cuneus. GM volume was significantly lower mainly in the right middle temporal gyrus in patients with MDD than in normal controls. We did not find any significant treatment-by-CM interactive effects. However, a treatment-related increase in GM was found in the right middle temporal gyrus in both MDD groups. CONCLUSIONS These results suggest that paroxetine treatment operates via a shared neurobiological mechanism in MDD patients with and without CM.

Abstract
INTRODUCTION Little is known about how exposure to adverse childhood experiences (ACEs) and protective factors, such as resilience, influence prenatal mental and behavioral health. This study examined associations between exposure to ACEs and mental and behavioral health during pregnancy overall and among women with high versus low levels of resilience. MATERIALS AND METHODS Women in two Kaiser Permanente Northern California medical centers were screened for ACEs and resilience during prenatal care (∼14-23 weeks of gestation; N = 355). Multivariable logistic regression analyses examined associations between ACEs and prenatal mental and behavioral health conditions overall and for women with low (≤32) versus high (>32) resilience on the 10-item Connor-Davidson Resilience Scale. RESULTS Overall, 54% of women reported 0 ACEs, 28% 1-2 ACEs, and 18% 3+ ACEs. Relative to women with 0 ACEs, those with 1-2 ACEs had higher odds of an anxiety or depressive disorder and intimate partner violence (IPV) (odds ratios [ORs] 2.42-3.12, p < 0.05), and those with 3+ ACEs had higher odds of an anxiety or depressive disorder, depression symptoms, and IPV (ORs 3.08-4.71, p < 0.05). In stratified analyses by high (56%) and low (44%) resilience, having one or more ACEs (vs. 0 ACEs) was only associated with worse mental and behavioral health in women with low resilience. CONCLUSIONS ACEs predicted mental and behavioral health conditions among pregnant women, and associations were the strongest among women with low levels of current resilience. Longitudinal research is needed to understand the causal mechanisms underlying these associations.

Abstract
Exposure to trauma in the childhood and abnormal interpersonal stress reactivity are believed to contribute to the pathophysiology of anorexia nervosa (AN), which suggests a possible role of the hypothalamus-pituitary adrenal (HPA) axis. Although an effect of early traumatic experiences on the cortisol awakening response has been proved in patients with AN, the consequences of childhood trauma exposure on HPA axis reactivity to psychosocial stressors has been never investigated in such individuals. Therefore, we have assessed emotional and cortisol responses to an acute psycho-social stress in AN patients with a history of childhood trauma exposure. Twenty-four AN women and 17 healthy women were enrolled in the study. Patients were classified as maltreated (Mal) or non-maltreated (noMal) according to their Childhood Trauma Questionnaire scores. Participants underwent the Trier Social Stress Test (TSST) and their emotional responses were measured through the state scale of the State-Trait Anxiety Inventory. Saliva samples were collected to measure cortisol production. Compared to both healthy subjects and noMal AN patients, Mal AN women exhibited a blunted cortisol response to TSST. With respect to healthy controls, pre-TSST anxiety levels were enhanced in both AN groups; moreover, Mal AN patients displayed a reduced anxiety increase after TSST as compared to both noMal patients and healthy women. Our findings for the first time provide the evidence of deranged biological and emotional responses to an acute social stress in AN patients with childhood trauma exposure, corroborating the idea of a maltreated ecophenotype in AN as in other psychiatric disorders.

Abstract
BACKGROUND Supportive parenting during childhood has been associated with many positive developmental outcomes for offspring in adulthood, including fewer health-risk behaviors. Little is known about the neural mechanisms underlying these associations. METHODS The present study followed rural African Americans (n = 91, 52% female) from late childhood (11-13 years of age) to emerging adulthood (25 years of age). Parent-child communication was assessed at 11, 12, and 13 years of age. Functional magnetic resonance imaging was used at 25 years of age to measure resting-state functional connectivity of the anterior salience network (ASN). Harmful alcohol use and emotional eating were also assessed at 25 years of age. Structural equation modeling was used to test pathways from parent-child communication at 11 to 13 years of age to harmful alcohol use and emotional eating at 25 years of age via resting-state functional connectivity of the ASN. RESULTS Greater parent-child communication between 11 and 13 years of age forecast greater resting-state functional connectivity of the ASN at 25 years of age which, in turn, was associated with lower harmful alcohol use and emotional eating at 25 years of age. Significant indirect effects through the ASN were present for both outcomes. CONCLUSIONS These findings indicate the importance of parenting in late childhood for adaptive behaviors and suggest a pathway via higher ASN coherence. This network was implicated in both harmful alcohol use and emotional eating, corroborating evidence of overlap in brain regions for dysregulated substance use and eating behaviors and revealing divergent pathways. These findings support the value of prevention and intervention efforts targeting parenting skills in childhood toward fostering long-term, adaptive neurocognitive development.

Abstract
Forcible separation and detention of children from parents seeking asylum in the United States has been decried as immoral and halted by court order. Babies and children have been separated and transported to facilities sometimes many miles away. Limited data on forced detention of unaccompanied minors reveal high incidence of posttraumatic stress, anxiety disorders, depression, aggression, and suicidal ideation. These consequences will be magnified in youths forcibly separated from their parents, particularly younger children who depend on attachment bonds for self-regulation and resilience. Studies exploring the neuropsychiatric consequences of traumatic stress have revealed consistent effects of early life stress on brain structure, function and connectivity, and the identification of sensitive periods, which occur throughout childhood when specific regions and pathways are strongly influenced by adversity. Studies of epigenetics, inflammation and allostatic load are similarly enhancing our awareness of the molecular mechanisms underpinning the long-term consequences of traumatic stress. We must consider effects on the developing brain, mind and body to appreciate the long-term consequences of policies that force separation and detention of children.

Abstract
It has long been assumed that social animals, such as humans, are born with a brain system that has evolved to support social affiliation. However, the evidence does not necessarily support this assumption. Alternatively, social animals can be defined as those who cannot survive alone and rely on members from their group to regulate their ongoing physiology (or allostasis). The rather simple evolutionary constraint of social dependency for survival can be sufficient to make the social environment vitally salient, and to provide the ultimate driving force for socially crafted brain development and learning. In this Perspective, we propose a framework for sociality and specify a set of hypotheses on the mechanisms of social development and underlying neural systems. The theoretical shift proposed here implies that profound human characteristics, including but not limited to sociality, are acquired at an early age, while social interactions provide key wiring instructions that determine brain development.

Abstract
BACKGROUND Cortical glutamatergic dysfunction is thought to be fundamental for psychosis development, and may lead to structural degeneration through excitotoxicity. Glutamate levels have been related to gray matter volume (GMV) alterations in people at ultra-high risk of psychosis, and we previously reported GMV changes in individuals with high schizotypy (HS), which refers to the expression of schizophrenia-like characteristics in healthy people. This study sought to examine whether GMV changes in HS subjects are related to glutamate levels. METHODS We selected 22 healthy subjects with HS and 23 healthy subjects with low schizotypy (LS) based on their rating on a self-report questionnaire for psychotic-like experiences. Glutamate levels were measured in the bilateral anterior cingulate cortex (ACC) using proton magnetic resonance spectroscopy, and GMV was assessed using voxel-based morphometry. RESULTS Subjects with HS showed GMV decreases in the rolandic operculum/superior temporal gyrus (pFWE = 0.045). Significant increases in GMV were also detected in HS, in the precuneus (pFWE = 0.043), thereby replicating our previous finding in a separate cohort, as well as in the ACC (pFWE = 0.041). While the HS and LS groups did not differ in ACC glutamate levels, in HS subjects ACC glutamate was negatively correlated with ACC GMV (pFWE = 0.026). Such association was absent in LS. CONCLUSIONS Our study shows that GMV findings in schizotypy are related to glutamate levels, supporting the hypothesis that glutamatergic function may lead to structural changes associated with the expression of psychotic-like experiences.

Abstract
Home visitation (HV) interventions may hold promise to improve parenting and prevent child maltreatment recidivism in families reported to child protective services (CPS) with young children, but this has rarely been studied. Findings are presented from an 18-month randomized controlled trial in which intact families ( N = 122) with at least one CPS report were provided with a facilitated connection to a paraprofessional evidence-based HV program or usual care services from child protection. Results are reported for changes in maternal stress, depression, and social support outcomes and repeat reports to CPS. No significant changes were found in maternal outcomes by group. Among nondepressed mothers or families without multiple CPS reports prior to study enrollment, HV was associated with a significantly lower likelihood of CPS report recidivism. These results indicate potential for HV to prevent maltreatment recidivism but suggest that higher intensity intervention is warranted for mothers exhibiting significant depressive symptoms or families with extensive CPS histories.

Abstract
Attachment theory was developed by John Bowlby in the 1950s. He defined attachment as a specific neurobiological system that resulted in the infant connecting to the primary caretaker in such a way to create an inner working model of relationships that continues throughout life and affects the future mental health and physical health of the infant. Given the significance of this inner working model, there has been a tremendous amount of research done in animals as well as humans to better understand the neurobiology. In this article the neurobiology of early development will be outlined with respect to the formation of attachment. This article will review what we have begun to understand as the neurobiology of attachment and will describe how the relationship with the primary caretaker affects the infant in a way leading to neurobiological changes that later in life affect emotional responses, reward, and perception difficulties that we recognize as psychiatric illness and medical morbidity.

Abstract
Early life stress (ELS) increases the risk for later cognitive and emotional dysfunction, and has been implicated in the etiology of multiple psychiatric disorders. We hypothesize that combined insults during gestation and infancy, critical periods of neural development, could exacerbate neuropsychiatric outcomes in later life. Thus, we investigated the effects of maternal deprivation (MD) stress alone or combined with prenatal nicotine exposure (PNE) on negative affective states, ethanol drinking, and development of mesolimbic loci that regulate depression and drug dependence. On the elevated plus maze (EPM), MD rats exhibited ∼50% increase in risk-taking behavior/decreased anxiety when compared to control, but the combined MD + PNE did not affect this specific behavior. In the open field test, however, both MD and MD + PNE groups showed 2-fold greater locomotor activity. Furthermore, whereas MD showed greater latency to fall at 40 RPM on the rotarod compared to control, the MD + PNE animals' latency to fall was significantly greater at all RPMs tested, with an approximate 15% enhancement in motor coordination overall compared to control and MD. Analyses of depressive symptomatology with the forced swim test (FST) yielded 2- and 3-fold higher immobility times in MD and MD + PNE respectively. When tested in an operant drinking paradigm to quantify the effect of treatment on 10%v/v ethanol drinking, the MD and MD + PNE groups showed heightened ethanol consumption by ∼3- and 2-fold respectively. However, the experience of PNE reduced ethanol consumption in adults relative to MD alone. To test the stressors' impact on neurons in the amygdala and ventral tegmental area (VTA), mesolimbic anatomical regions associated with mood and reward, unbiased stereological measurements were performed and revealed ∼15% increase in number and density of neurons in the amygdala for both MD and MD + PNE, and ∼13% reduction in dopaminergic-like neurons in the VTA compared to control. We report here that multiple early stressors including prenatal nicotine and MD can modulate the neuroanatomy of the amygdala and VTA. These early life stressors can interact to influence the development of depressive-like and addictive behaviors.

Abstract
Reactive attachment disorder (RAD) is a severe social functioning disorder associated with early childhood maltreatment where the child displays emotionally withdrawn/inhibited behaviors toward caregivers. Brain regions develop at different rates and regions undergoing rapid change may be particularly vulnerable during these times to stressors or adverse experiences. The aim of this study was to investigate the effect of type and timing of childhood adversities on structural alterations in regional gray matter (GM) volume in maltreated children with RAD. High-resolution magnetic resonance imaging datasets were obtained for children and adolescents with RAD (n = 21; mean age = 12.76 years) and typically developing (TD) control subjects (n = 22; mean age = 12.95 years). Structural images were analyzed using a whole-brain voxel-based morphometry approach and the type and timing of maltreatment, which may be more strongly associated with structural alterations, was assessed using random forest regression with conditional inference trees. Our findings revealed that there is a potential sensitive period between 5 and 7 years of age for GM volume reduction of the left primary visual cortex (BA17) due to maltreatment. We also found that the number of types of maltreatment had the most significant effect on GM volume reduction and that the second most significant variable was exposure to neglect. The present study provides the first evidence showing that type and timing of maltreatment have an important role in inducing structural abnormalities in children and adolescents with RAD.

Abstract
Individuals who have prior history of childhood traumatic experiences are at a high risk for a variety of psychological and behavioral problems throughout their lifetime. This study aimed to investigate whether such individuals exhibit altered cortical functional networks during a behavioral inhibition task. One hundred fifty-three non-clinical individuals were recruited and instructed to perform a Go/NoGo task during an electroencephalograph. Source-level weighted functional networks based on the graph theory were analyzed for NoGo-P3 processing. Based on their total scores on the childhood trauma questionnaire (CTQ) participants were divided into three groups: low CTQ, middle CTQ, and high CTQ. Results at the global level indicated decreased strength, clustering coefficient, and efficiency for the low and gamma bands in the high CTQ group. In addition, the path length of the low beta band was observed to be longer in the high CTQ group than the low CTQ group. At the nodal level, the nodal clustering coefficient of high CTQ group was decreased in left primary somatosensory cortex and middle occipital gyrus for the low beta band, and in left superior temporal gyrus for the gamma band. The nodal clustering coefficient of the left primary somatosensory cortex showed a significant negative correlation with the total CTQ score for the low beta band. In addition, the nodal clustering coefficient of the left middle occipital gyrus for the low beta band and superior temporal gyrus for the gamma band showed significant negative correlations with the emotional neglect score. Our results demonstrate an altered cortical functional network in individuals who experienced childhood trauma. In particular, the left primary somatosensory cortex, middle occipital gyrus, and superior temporal gyrus were found to be vulnerable in individuals who experienced childhood trauma, especially emotional neglect.

Abstract
Available treatment methods have shown little effect on the burden associated with mental health disorders. We review promising universal, selective, and indicated preventive mental health strategies that might reduce the incidence of mental health disorders, or shift expected trajectories to less debilitating outcomes. Some of these interventions also seem to be cost-effective. In the transition to mental illness, the cumulative lifetime effect of multiple small effect size risk factors progressively increases vulnerability to mental health disorders. This process might inform different levels and stages of tailored interventions to lessen risk, or increase protective factors and resilience, especially during sensitive developmental periods. Gaps between knowledge, policy, and practice need to be bridged. Future steps should emphasise mental health promotion, and improvement of early detection and interventions in clinical settings, schools, and the community, with essential support from society and policy makers.

Abstract
Mothers with a substance use disorder (SUD) are at risk for maladaptive parenting practices, and have heightened likelihood of having experienced childhood adversity themselves. In addition, parental reflective functioning (PRF), a capacity underlying sensitive caregiving, is often low in mothers with SUD. This study examines the relationship between PRF and aversive (emotional, physical, sexual abuse and neglect) and adaptive (safety and competence) experiences, in different developmental phases (early childhood, latency, and adolescence) in mothers with a SUD. A sample of 43 mothers with small children were interviewed with the Parental Developmental Interview to assess PRF, and they completed the Traumatic Antecedents Questionnaire regarding aversive and adaptive experiences. In addition, we used the Hopkins Symptoms Checklist-10 to control for mental health status and a battery of neuropsychological tests to control for executive functions. Results indicated that adaptive experiences in early childhood were positively related to PRF, and that experience of emotional abuse was negatively related to PRF. When separating the group of mothers in two sub-groups based on PRF level, results showed that mothers with negative to low PRF had significantly more experiences of adversities in early childhood and latency, and significantly less adaptive experiences in early childhood, latency and adolescence, compared to mothers with moderate to high PRF. In addition, mothers with adequate to high PRF reported experiencing significantly more types of adaptive experiences, and significantly less adversities compared to mothers with negative to low PRF. Results are discussed in relation to developmental trauma, resilience, epistemic trust and mistrust.

Abstract
BACKGROUND Childhood trauma is a risk factor for psychosis. Deficits in response inhibition are common to psychosis and trauma-exposed populations, and associated brain functions may be affected by trauma exposure in psychotic disorders. We aimed to identify the influence of trauma-exposure on brain activation and functional connectivity during a response inhibition task. METHODS We used functional magnetic resonance imaging to examine brain function within regions-of-interest [left and right inferior frontal gyrus (IFG), right dorsolateral prefrontal cortex, right supplementary motor area, right inferior parietal lobule and dorsal anterior cingulate cortex], during the performance of a Go/No-Go Flanker task, in 112 clinical cases with psychotic disorders and 53 healthy controls (HCs). Among the participants, 71 clinical cases and 21 HCs reported significant levels of childhood trauma exposure, while 41 clinical cases and 32 HCs did not. RESULTS In the absence of effects on response inhibition performance, childhood trauma exposure was associated with increased activation in the left IFG, and increased connectivity between the left IFG seed region and the cerebellum and calcarine sulcus, in both cases and healthy individuals. There was no main effect of psychosis, and no trauma-by-psychosis interaction for any other region-of-interest. Within the clinical sample, the effects of trauma-exposure on the left IFG activation were mediated by symptom severity. CONCLUSIONS Trauma-related increases in activation of the left IFG were not associated with performance differences, or dependent on clinical diagnostic status; increased IFG functionality may represent a compensatory (overactivation) mechanism required to exert adequate inhibitory control of the motor response.

Abstract
BACKGROUND Adverse childhood experiences (ACEs) including maltreatment and exposure to household stressors can impact the health of children. Community factors that provide support, friendship and opportunities for development may build children's resilience and protect them against some harmful impacts of ACEs. We examine if a history of ACEs is associated with poor childhood health and school attendance and the extent to which such outcomes are counteracted by community resilience assets. METHODS A national (Wales) cross-sectional retrospective survey (n = 2452) using a stratified random probability sampling methodology and including a boost sample (n = 471) of Welsh speakers. Data collection used face-to-face interviews at participants' places of residence. Outcome measures were self-reported poor childhood health, specific conditions (asthma, allergies, headaches, digestive disorders) and school absenteeism. RESULTS Prevalence of each common childhood condition, poor childhood health and school absenteeism increased with number of ACEs reported. Childhood community resilience assets (being treated fairly, supportive childhood friends, being given opportunities to use your abilities, access to a trusted adult and having someone to look up to) were independently linked to better outcomes. In those with ≥4 ACEs the presence of all significant resilience assets (vs none) reduced adjusted prevalence of poor childhood health from 59.8 to 21.3%. CONCLUSIONS Better prevention of ACEs through the combined actions of public services may reduce levels of common childhood conditions, improve school attendance and help alleviate pressures on public services. Whilst the eradication of ACEs remains unlikely, actions to strengthen community resilience assets may partially offset their immediate harms.

Abstract
Animal and human studies have shown that both early-life traumatic events and ongoing stress episodes affect neurodevelopment, however, it remains unclear whether and how they modulate normative adolescent neuro-maturational trajectories. We characterized effects of early-life (age 0-5) and ongoing stressors (age 14-17) on longitudinal changes (age 14 to17) in grey matter volume (GMV) of healthy adolescents (n = 37). Timing and stressor type were related to differential GMV changes. More personal early-life stressful events were associated with larger developmental reductions in GMV over anterior prefrontal cortex, amygdala and other subcortical regions; whereas ongoing stress from the adolescents' social environment was related to smaller reductions over the orbitofrontal and anterior cingulate cortex. These findings suggest that early-life stress accelerates pubertal development, whereas an adverse adolescent social environment disturbs brain maturation with potential mental health implications: delayed anterior cingulate maturation was associated with more antisocial traits - a juvenile precursor of psychopathy.

Abstract
Early life stress (ELS) is a significant risk factor for the emergence of internalizing problems in adolescence. Beginning in adolescence, females are twice as likely as males to experience internalizing disorders. The present study was designed to examine sex differences in the association between ELS and internalizing problems in early pubertal adolescents, and whether and how corticolimbic function and connectivity may underlie these associations. Fifty-nine early pubertal males and 78 early pubertal females, ages 9-13 years (all Tanner Stage 3 or below) underwent functional magnetic resonance imaging as they performed an emotion label task that robustly interrogates corticolimbic function. Participants were also interviewed about their experience of ELS. Females exhibited a positive association between ELS and internalizing problems, whereas males exhibited no such association. Whole-brain and amygdala region of interest analyses indicated that whereas females exhibited a positive association between ELS and the ventrolateral prefrontal cortex during implicit emotion regulation, males showed no such association. Activation in these regions was positively associated with internalizing problems in females but not males; however, activation in these regions did not mediate the association between ELS and internalizing problems. Finally, both boys and girls exhibited an association between ELS and increased negative connectivity between the right ventrolateral prefrontal cortex and bilateral amygdala. Using a carefully characterized sample of early pubertal adolescents, the current study highlights important sex differences in the development of corticolimbic circuitry during a critical period of brain development. These sex differences may play a significant role in subsequent risk for internalizing problems.

Abstract
The association of childhood maltreatment and suicide has been extensively examined within the population. Depression figures as a main cause for the elevated suicide rate in advanced ages and is often related to childhood maltreatment. The purpose of the present study was to examine the relationship between childhood maltreatment subtypes and suicide risk, testing geriatric depression as a moderator. This is a cross-sectional study looking at a sample of 449 individuals 60 year s old or older from the Multidimensional Study of the Elderly of Porto Alegre Family Health Strategy, Brazil (EMI-SUS/POA). Childhood maltreatment (Childhood Trauma Questionnaire), geriatric depressive symptoms (Geriatric Depression Scale), and suicide risk (Mini International Neuropsychiatric Interview) were assessed. The subtypes of childhood abuse and neglect were significantly associated with suicide risk. In the multivariate analysis, controlling for age, gender, income, marital status, ethnicity, smoking, and geriatric depression symptoms, all trauma subtypes remained associated with suicide risk with the exception of physical neglect (EA = 3.65; PA = 3.16; SA = 5.1; EN = 2.43; PN = 1.76). The present study showed that childhood maltreatment subtypes predicted suicide risk, and geriatric depression does not directly mediate this relation.

Abstract
This study aims to examine the extent to which a variety of pre-delivery factors (demographic, reproductive, psychological, psychiatric, and psychopathological) predict disturbances in mother-infant bonding (MIB) in the postpartum period. Two hundred fifty-one pregnant women enrolled at a public perinatal psychiatric service were assessed between the first and second trimester of pregnancy and at 6-7 weeks after delivery. During pregnancy, the psychological risk factors were assessed with the Vulnerable Personality Style Questionnaire, the Marital Adjustment Scale, the Early Trauma Inventory, and the General Health Questionnaire. To detect psychopathology, the Edinburgh Postnatal Depression Scale and the State-Trait Anxiety Inventory were used. At the postpartum evaluation, MIB was measured by the Postpartum Bonding Questionnaire. The results of the final regression model showed that emotional abuse in childhood, family psychiatric history, previous psychiatric hospitalization, and anxiety during pregnancy were significant predictors of MIB disturbances in postpartum, explaining 10.7% of the variance. The evaluation of women's risk factors in pregnancy is important in order to prevent MIB disturbances and thus to ensure the welfare of mothers and their babies.

Neurodevelopmental consequences of pediatric cancer and its treatment: applying an early adversity framework to understanding cognitive, behavioral, and emotional outcomes.

Abstract
Today, children are surviving pediatric cancer at unprecedented rates, making it one of modern medicine's true success stories. However, we are increasingly becoming aware of several deleterious effects of cancer and the subsequent "cure" that extend beyond physical sequelae. Indeed, survivors of childhood cancer commonly report cognitive, emotional, and psychological difficulties, including attentional difficulties, anxiety, and posttraumatic stress symptoms (PTSS). Cognitive late- and long-term effects have been largely attributed to neurotoxic effects of cancer treatments (e.g., chemotherapy, cranial irradiation, surgery) on brain development. The role of childhood adversity in pediatric cancer - namely, the presence of a life-threatening disease and endurance of invasive medical procedures - has been largely ignored in the existing neuroscientific literature, despite compelling research by our group and others showing that exposure to more commonly studied adverse childhood experiences (i.e., domestic and community violence, physical, sexual, and emotional abuse) strongly imprints on neural development. While these adverse childhood experiences are different in many ways from the experience of childhood cancer (e.g., context, nature, source), they do share a common element of exposure to threat (i.e., threat to life or physical integrity). Therefore, we argue that the double hit of early threat and cancer treatments likely alters neural development, and ultimately, cognitive, behavioral, and emotional outcomes. In this paper, we (1) review the existing neuroimaging research on child, adolescent, and adult survivors of childhood cancer, (2) summarize gaps in our current understanding, (3) propose a novel neurobiological framework that characterizes childhood cancer as a type of childhood adversity, particularly a form of early threat, focusing on development of the hippocampus and the salience and emotion network (SEN), and (4) outline future directions for research.

Abstract
Cognitive control, which relies on the protracted development of frontal-parietal regions into adolescence, is a brain process that may be particularly vulnerable to the impact of childhood abuse. In this study, we used functional magnetic resonance imaging (fMRI) to examine associations between the age of onset of childhood abuse and alterations to the neural mechanisms supporting cognitive control in early adulthood, which have not been previously examined. During fMRI scanning, participants completed hybrid block/event-related versions of a classic color-word Stroop task as well as emotional Stroop tasks (threat and positive words). Participants were young adult women (N = 15; age range: 23-30 years) who had a history of childhood physical or sexual abuse that began prior to 13 years of age. Results indicated that earlier age of onset of childhood abuse was robustly associated with increased transient (i.e., event-related) recruitment of medial cognitive control regions in the classic color-word paradigm as well as with less suppression of medial frontal regions that are part of the default mode network, βs = -.16 to -.87. In comparison, increased activation in dorsolateral prefrontal regions was associated with earlier age of abuse onset under conditions of sustained (i.e., blocked) cognitive control in the emotional Stroop task for blocks of positive distracting words versus fixation, βs = -.50 to -.60. These results provide preliminary evidence that earlier age of exposure to childhood abuse impacts the functional activation of neural systems involved in cognitive control in adulthood.

Abstract
Previous research suggests that exposure to early life stress (ELS) affects the structural integrity of the uncinate fasciculus (UF), a frontolimbic white matter tract that undergoes protracted development throughout adolescence. Adolescence is an important transitional period characterized by the emergence of internalizing psychopathology such as anxiety, particularly in individuals with high levels of stress sensitivity. We examined the relations among sensitivity to ELS, structural integrity of the UF, and anxiety symptoms in 104 early adolescents. We conducted structured interviews to assess exposure to ELS and obtained subjective and objective ratings of stress severity, from which we derived an index of ELS sensitivity. We also acquired diffusion MRI and conducted deterministic tractography to visualize UF trajectories and to compute measures of structural integrity from three distinct segments of the UF: frontal, insular, temporal. We found that higher sensitivity to ELS predicted both reduced fractional anisotropy in right frontal UF and higher levels of anxiety symptoms. These findings suggest that fibers in frontal UF, which are still developing throughout adolescence, are most vulnerable to the effects of heightened sensitivity to ELS, and that reduced structural integrity of frontal UF may underlie the relation between early stress and subsequent internalizing psychopathology.

Abstract
INTRODUCTION Previous meta-analyses have shown a moderate negative impact of maltreatment on the neuropsychological functioning of people with or without psychiatric disorders compared to healthy groups. The objectives of the present meta-analysis were to (1) investigate the impact of maltreatment on neuropsychological functioning of people with psychiatric disorders and to (2) evaluate the moderating effect of age, at the time of the cognitive assessment, on neuropsychological functioning. METHODS Seventeen studies published between 1970 and July 2017 were included. RESULTS The results showed a negative impact of maltreatment with a small effect size (g = -0.25) on the neuropsychological performances in the group with psychiatric disorders with a history of exposure to childhood maltreatment compared to the group with psychiatric disorders without a history of exposure to childhood maltreatment. Cognitive domains that are significantly affected by maltreatment are: working memory (g = -0.56), verbal episodic memory (g = -0.39), intelligence (g = -0.27) and processing speed (g = -0.21). The impact of childhood maltreatment on the cognitive profile is greater in adults than young people. CONCLUSIONS Clinicians should consider these common cognitive deficits using a transdiagnostic approach in cognitive interventions.

Abstract
BACKGROUND Exposure to threat-related early life stress (ELS) has been related to vulnerability for stress-related disorders in adulthood, putatively via disrupted corticolimbic circuits involved in stress response and regulation. However, previous research on ELS has not examined both the intrinsic strength and flexibility of corticolimbic circuits, which may be particularly important for adaptive stress responding, or associations between these dimensions of corticolimbic dysfunction and acute stress response in adulthood. METHODS Seventy unmedicated women varying in history of threat-related ELS completed a functional magnetic resonance imaging scan to evaluate voxelwise static (overall) and dynamic (variability over a series of sliding windows) resting-state functional connectivity (RSFC) of bilateral amygdala. In a separate session and subset of participants (n = 42), measures of salivary cortisol and affect were collected during a social-evaluative stress challenge. RESULTS Higher severity of threat-related ELS was related to more strongly negative static RSFC between amygdala and left dorsolateral prefrontal cortex (DLPFC), and elevated dynamic RSFC between amygdala and rostral anterior cingulate cortex (rACC). Static amygdala-DLPFC antagonism mediated the relationship between higher severity of threat-related ELS and blunted cortisol response to stress, but increased dynamic amygdala-rACC connectivity weakened this mediated effect and was related to more positive post-stress mood. CONCLUSIONS Threat-related ELS was associated with RSFC within lateral corticolimbic circuits, which in turn was related to blunted physiological response to acute stress. Notably, increased flexibility between the amygdala and rACC compensated for this static disruption, suggesting that more dynamic medial corticolimbic circuits might be key to restoring healthy stress response.

Abstract
Child maltreatment is a major cause of pediatric posttraumatic stress disorder (PTSD). Previous studies have not investigated potential differences in network architecture in maltreated youth with PTSD and those resilient to PTSD. High-resolution magnetic resonance imaging brain scans at 3 T were completed in maltreated youth with PTSD (n = 31), without PTSD (n = 32), and nonmaltreated controls (n = 57). Structural covariance network architecture was derived from between-subject intraregional correlations in measures of cortical thickness in 148 cortical regions (nodes). Interregional positive partial correlations controlling for demographic variables were assessed, and those correlations that exceeded specified thresholds constituted connections in cortical brain networks. Four measures of network centrality characterized topology, and the importance of cortical regions (nodes) within the network architecture were calculated for each group. Permutation testing and principle component analysis method were employed to calculate between-group differences. Principle component analysis is a methodological improvement to methods used in previous brain structural covariance network studies. Differences in centrality were observed between groups. Larger centrality was found in maltreated youth with PTSD in the right posterior cingulate cortex; smaller centrality was detected in the right inferior frontal cortex compared to youth resilient to PTSD and controls, demonstrating network characteristics unique to pediatric maltreatment-related PTSD. Larger centrality was detected in right frontal pole in maltreated youth resilient to PTSD compared to youth with PTSD and controls, demonstrating structural covariance network differences in youth resilience to PTSD following maltreatment. Smaller centrality was found in the left posterior cingulate cortex and in the right inferior frontal cortex in maltreated youth compared to controls, demonstrating attributes of structural covariance network topology that is unique to experiencing maltreatment. This work is the first to identify cortical thickness-based structural covariance network differences between maltreated youth with and without PTSD. We demonstrated network differences in both networks unique to maltreated youth with PTSD and those resilient to PTSD. The networks identified are important for the successful attainment of age-appropriate social cognition, attention, emotional processing, and inhibitory control. Our findings in maltreated youth with PTSD versus those without PTSD suggest vulnerability mechanisms for developing PTSD.

Abstract
BACKGROUND Childhood abuse is associated with abnormalities in brain structure and function. Few studies have investigated abuse-related brain abnormalities in medication-naïve, drug-free youth that also controlled for psychiatric comorbidities by inclusion of a psychiatric control group, which is crucial to disentangle the effects of abuse from those associated with the psychiatric conditions. METHODS Cortical volume (CV), cortical thickness (CT) and surface area (SA) were measured in 22 age- and gender-matched medication-naïve youth (aged 13-20) exposed to childhood abuse, 19 psychiatric controls matched for psychiatric diagnoses and 27 healthy controls. Both region-of-interest (ROI) and whole-brain analyses were conducted. RESULTS For the ROI analysis, the childhood abuse group compared with healthy controls only, had significantly reduced CV in bilateral cerebellum and reduced CT in left insula and right lateral orbitofrontal cortex (OFC). At the whole-brain level, relative to healthy controls, the childhood abuse group showed significantly reduced CV in left lingual, pericalcarine, precuneus and superior parietal gyri, and reduced CT in left pre-/postcentral and paracentral regions, which furthermore correlated with greater abuse severity. They also had increased CV in left inferior and middle temporal gyri relative to healthy controls. Abnormalities in the precuneus, temporal and precentral regions were abuse-specific relative to psychiatric controls, albeit at a more lenient level. Groups did not differ in SA. CONCLUSIONS Childhood abuse is associated with widespread structural abnormalities in OFC-insular, cerebellar, occipital, parietal and temporal regions, which likely underlie the abnormal affective, motivational and cognitive functions typically observed in this population.

Abstract
Child maltreatment is a global problem affecting millions of children and is associated with an array of cumulative negative outcomes later in life, including unemployment and financial difficulties. Although establishing child maltreatment as a causal mechanism for adult economic outcomes is fraught with difficulty, understanding the relationship between the two is essential to reducing such inequality. This paper presents findings from a systematic review of longitudinal research examining experiences of child maltreatment and economic outcomes in adulthood. A systematic search of seven databases found twelve eligible retrospective and prospective cohort studies. From the available evidence, there was a relatively clear relationship between 'child maltreatment' and poorer economic outcomes such as reduced income, unemployment, lower level of job skill and fewer assets, over and above the influence of family of origin socio-economic status. Despite an extremely limited evidence base, neglect had a consistent relationship with a number of long-term economic outcomes, while physical abuse has a more consistent relationship with income and employment. Studies examining sexual abuse found less of an association with income and employment, although they did find a relationship other outcomes such as sickness absence, assets, welfare receipt and financial insecurity. Nonetheless, all twelve studies showed some association between at least one maltreatment type and at least one economic measure. The task for future research is to clarify the relationship between specific maltreatment types and specific economic outcomes, taking account of how this may be influenced by gender and life course stage.

Abstract
Objective Reduced hippocampal volume and alterations in white matter tracts have been frequently reported in adults having the history of emotional maltreatment. We investigated whether these structural change occur in adolescents with previous verbal abuse (VA) experiences. Methods Hippocampal subfield volume and white matter structural connectivity measures were assessed in 31 first year male high school students with various degrees of exposure to parental and peer VA. Results The high VA group showed significant volume reduction in the left cornu ammonis (CA) 1 and left subiculum compared to the low VA group (p<0.05). Volumes of left hippocampal subfields CA1 and subiculum were negatively correlated with previous VA experiences (p<0.05). Increased mean diffusivity (MD) of the splenium of the corpus callosum was related to high VA score across all subjects (p<0.05). There was an inverse relationship between volume of the CA1 and subiculum and MD of the splenium (p<0.05). Conclusion Exposure to parental and peer VA may affect development of the left hippocampal subfields and the splenium of corpus callosum. These structural alterations can be discernible during adolescence.

Front Hum Neurosci 2018; 12:51. [PMID: 29497369 PMCID: PMC5818418 DOI: 10.3389/fnhum.2018.00051] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Accepted: 01/31/2018] [Indexed: 11/30/2022] Open
Abstract
Background: Childhood trauma affects neurodevelopment and promotes vulnerability to impaired constraint, depression, and addiction. Reduced gray matter concentration (GMC) in the mesocorticolimbic regions implicated in reward processing and cognitive control may be an underlying substrate, as documented separately in addiction and for childhood trauma. The purpose of this study was to understand the contribution of childhood maltreatment to GMC effects in individuals with cocaine use disorder. Methods: Individuals with cocaine use disorder were partitioned into groups of low vs. high childhood trauma based on median split of the total score of the Childhood Trauma Questionnaire (CTQ; CUD-L, N = 23; CUD-H, N = 24) and compared with age, race, and gender matched healthy controls with low trauma (N = 29). GMC was obtained using voxel-based morphometry applied to T1-weighted MRI scans. Drug use, depression and constraint were assessed with standardized instruments. Results: Whole-brain group comparisons showed reduced GMC in the right lateral orbitofrontal cortex (OFC) in CUD-H as compared with controls (cluster-level pFWE-corr < 0.001) and CUD-L (cluster-level pFWE-corr = 0.035); there were no significant differences between CUD-L and controls. A hierarchical regression analysis across both CUD groups revealed that childhood trauma, but not demographics and drug use, and beyond constraint and depression, accounted for 37.7% of the variance in the GMC in the right lateral OFC (p < 0.001). Conclusions: Beyond other contributing factors, childhood trauma predicted GMC reductions in the OFC in individuals with cocaine use disorder. These findings underscore a link between premorbid environmental stress and morphological integrity of a brain region central for behaviors underlying drug addiction. These results further highlight the importance of accounting for childhood trauma, potentially as a factor predisposing to addiction, when examining and interpreting neural alterations in cocaine addicted individuals.

Abstract
Background Maternal separation models in rodents are widely used to establish molecular mechanisms underlying prolonged effects of early life adversity on neurobiological and behavioral outcomes in adulthood. However, global epigenetic signatures following early life stress in these models remain unclear. Results In this study, we carried out a ChIP-seq analysis of H3K4 trimethylation profile in the prefrontal cortex of adult male mice with a history of early life stress. Two types of stress were used: prolonged separation of pups from their mothers (for 3 h once a day, maternal separation, MS) and brief separation (for 15 min once a day, handling, HD). Adult offspring in the MS group demonstrated reduced locomotor activity in the open field test accompanied by reduced exploratory activity, while the HD group showed decreased anxiety-like behavior only. In a group of maternal separation, we have found a small number (45) of slightly up-regulated peaks, corresponding to promoters of 70 genes, while no changes were observed in a group of handling. Among the genes whose promoters have differential enrichment of H3K4me3, the most relevant ones participate in gene expression regulation, modulation of chromatin structure and mRNA processing. For two genes, Ddias and Pip4k2a, increased H3K4me3 levels were associated with the increased mRNA expression in MS group. Conclusion The distribution of H3K4me3 in prefrontal cortex showed relatively low variability across all individuals, and only some subtle changes were revealed in mice with a history of early life stress. It is possible that the observed long-lasting behavioral alterations induced by maternal separation are mediated by other epigenetic mechanisms, or other brain structures are responsible for these effects.

Abstract
Exposure to stress, particularly in periods of rapid brain maturation such as adolescence, can profoundly influence developmental processes that undergird the organization of structural and functional brain networks and that may mediate the association between stressful experiences and maladaptive outcomes. While studies in translational developmental neuroscience often focus on how specific brain regions or targeted connections are altered by stress and psychiatric disease, the emerging field of network science may be especially valuable for elucidating the impact of stress on the intricate connectomics of the adolescent brain. Here we review recent studies that use graph theory and other network science approaches to understand normative adolescent brain development, effects of childhood maltreatment on the brain, and disorders characterized by pathological responses to stress in adolescents. Overall, these studies demonstrate that graph theory can be useful in identifying and quantifying developmental processes related to segregation, integration, and localized hub influence that are affected by stress exposure and that may lead to psychopathology. Finally, we discuss limitations in the current application of graph theory in this area and suggest what we believe are important directions for future work.

Abstract
GABA plays a key role in both embryonic and neonatal brain development. For example, during early neonatal nervous system maturation, synaptic transmission, mediated by GABAA receptors (GABAA Rs), undergoes a temporally specific form of synaptic plasticity to accommodate the changing requirements of maturing neural networks. Specifically, the duration of miniature inhibitory postsynaptic currents (mIPSCs), resulting from vesicular GABA activating synaptic GABAA Rs, is reduced, permitting neurones to appropriately influence the window for postsynaptic excitation. Conventionally, programmed expression changes to the subtype of synaptic GABAA R are primarily implicated in this plasticity. However, it is now evident that, in developing thalamic and cortical principal- and inter-neurones, an endogenous neurosteroid tone (eg, allopregnanolone) enhances synaptic GABAA R function. Furthermore, a cessation of steroidogenesis, as a result of a lack of substrate, or a co-factor, appears to be primarily responsible for early neonatal changes to GABAergic synaptic transmission, followed by further refinement, which results from subsequent alterations of the GABAA R subtype. The timing of this cessation of neurosteroid influence is neurone-specific, occurring by postnatal day (P)10 in the thalamus but approximately 1 week later in the cortex. Neurosteroid levels are not static and change dynamically in a variety of physiological and pathophysiological scenarios. Given that GABA plays an important role in brain development, abnormal perturbations of neonatal GABAA R-active neurosteroids may have not only a considerable immediate, but also a longer-term impact upon neural network activity. Here, we review recent evidence indicating that changes in neurosteroidogenesis substantially influence neonatal GABAergic synaptic transmission. We discuss the physiological relevance of these findings and how the interference of neurosteroid-GABAA R interaction early in life may contribute to psychiatric conditions later in life.

Abstract
BACKGROUND Exposure to adverse childhood experiences (ACE) and cognitive deficits are both prevalent in psychosis. While it has been repeatedly demonstrated that ACE contribute to cognitive dysfunctions, the specific nature of this contribution remains elusive. Recent evidence suggests that types of adversities during critical periods have deleterious effects on brain structures that are important for cognitive functioning. The present study sought to clarify which types of adversities experienced at which time during development aggravate cognitive deficits in psychosis. METHODS Exposure to abuse and neglect during childhood and adolescence were retrospectively assessed in N=168 adult individuals with psychotic disorder. Conditioned random forest regression was used to define the importance of type and timing of ACE for predicting domains of the MATRICS Consensus Cognitive Battery (MCCB). RESULTS Significant importance of ACE was determined for 5 out of 7 MCCB domains. Particularly abuse at age 3 contributed to dysfunctional cognitive domains attention, learning, and working memory. Social cognition was related to neglect experienced at 11-12years, and to cumulative ACE. CONCLUSION Abuse and neglect at periods when children spend substantial time in their families affect cognitive functioning, and hence aggravate dysfunction in psychosis. Results support the neurodevelopmental perspective on psychosis and the diagnostic value of type and timing of ACE.

Abstract
Post-traumatic stress disorder (PTSD) is a mental disorder that may develop after exposure to exceptionally threatening or unescapable horrifying events. Actual therapies fail to alleviate the emotional suffering and cognitive impairment associated with this disorder, mostly because they are ineffective in treating the failure to extinguish trauma memories in a great percentage of those affected. In this review, current behavioral, cellular, and molecular evidence supporting the use of cotinine for treating PTSD are reviewed. The role of the positive modulation by cotinine of the nicotinic acetylcholine receptors (nAChRs) and their downstream effectors, the protection of astroglia, and the inhibition of microglia in the PTSD brain are also discussed.

Abstract
Individual differences in a child's sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n = 121, ages 9-16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child's trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments.

Abstract
Human and animal models suggest that maternal hormonal and physiological adaptations during pregnancy shape maternal brain functioning and behavior crucial for offspring care and survival. Less sensitive maternal behavior, often associated with psychobiological dysregulation and the offspring's behavioral and emotional disorders, has been observed in mothers who have experienced adverse childhood experiences. Strong evidence shows that children who are exposed to domestic violence (DV) are at risk of being abused or becoming abusive in adulthood. Yet little is known about the effect of childhood exposure to DV on the expecting mother, her subsequent caregiving behavior and related effects on her infant. Thus, the present study examined the association of maternal exposure to DV during childhood on prenatal maternal attachment, maternal heart rate reactivity to an infant-crying stimulus and post-natal infant emotional regulation. Thirty-three women with and without exposure to DV during childhood were recruited during the first trimester of pregnancy and followed until 6-month after birth. The Maternal Antenatal Attachment Scale (MAAS) was used to measure prenatal attachment of the mother to her fetus during the second trimester of pregnancy, maternal and fetal heart rate reactivity to an infant-crying stimulus was assessed at the third trimester of pregnancy, and the Infant Behavior Questionnaire-Revised (IBQ-R) was used to assess infant emotional regulation at 6-months. Results showed that pregnant women that were exposed to DV during childhood had a poorer quality of prenatal attachment of mother to fetus, regardless of whether they also experienced DV during adulthood. In addition, maternal exposure to DV during childhood was associated with increased maternal heart rate to infant-crying stimulus and worse infant emotional regulation. These findings highlight the importance of prenatal screening for maternal exposure to DV during childhood as a risk factor for disturbances in the development of maternal attachment, dysfunctional maternal behavior and emotion dysregulation.

Abstract
BACKGROUND Both environmental and genetic conditions contribute to the robust development of neuronal circuits and adulthood behaviors. Loss of motopsin gene function causes severe intellectual disability in humans and enhanced social behavior in mice. Furthermore, childhood maltreatment is a risk factor for some psychiatric disorders, and children with disabilities have a higher risk of abuse than healthy children. MATERIALS AND METHODS In this study, we investigated the effects of maternal separation (MS) on adulthood behaviors of motopsin knockout (KO) and wild-type (WT) mice. RESULTS The MS paradigm decreased the duration that WT mice stayed in the center area of an open field, but not for motopsin KO mice; however, it decreased the novel object recognition index in both genotypes. In the marble burying test, motopsin KO mice buried fewer marbles than WT mice, regardless of the rearing conditions. The MS paradigm slightly increased and reduced open arm entry in the elevated plus maze by WT and motopsin KO mice, respectively. In the three-chamber test, the rate of sniffing the animal cage was increased by the MS paradigm only for motopsin KO mice. After the three-chamber test, motopsin KO mice had fewer cFos-positive cells in the prelimbic cortex, which is involved in emotional response, than WT mice. In the infralimbic cortex, the MS paradigm decreased the number of cFos-positive cells in motopsin KO mice. CONCLUSION Our results suggest that motopsin deficiency and childhood adversity independently affect some behaviors, but they may interfere with each other for other behaviors. Defective neuronal circuits in the prefrontal cortex may add to this complexity.
